laden air fromthe inlet to the outlet chamber aboveor below the screens.At their front edges the'soreens are supported on the beam a. Theseframes are secured together in pairs along their top and bottom andfront edges by strips 1, 2, 3. The rear edges of inner frames ofadjacent pairs are secured together by the strips 4:. Thus the airentering the casing passes in between the pairs of frames, through thegauze, and into the outlet chamber. Thus there is provided a very largescreen surface in a small space and a plurality of compartments openingin opposite directions.

In securing the strips 1, 2, 3, 4, to the edges of the frames I groovethem as indicated at cl and stretch a strip of gauze d around over thegrooves. The edges of the frames which are rounded to fit the groovesare then forced into the grooves and the strips secured in place, thusforming a tight joint which will prevent the escape ofdust laden airexcept through the screens 0 The dust will gather on the screens and itis necessary to shake it off, which I do by hanging fairly heavy weightsor beams E on suitable swinging supports E, the latter pivoted to saidsupport a and providing To all whom it may concern:

Be it known that I, GEORGE WV. GHRISTOPH, a citizen of the United Statesof America, residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inSeparators, of which the following is a specification. Y

The object of my invention is to produce a device for cleaning air byseparating out the dust and solid matter.

In the drawings: Figure 1 is a plan view showing the screens-in sectionon the line 1-1 of Fig. 2. Fig. 2 is a sectional eleva tion. Fig. 3 is adetail sectional view in side elevation as indicated by the arrow 3.Fig. 4 is a detail plan view showing the method of connecting the screenframes.

In carrying out my invention I make use of a casing a, which, as shownin the drawings, is of rectangular shape, having an inlet a at one endand an outlet a at the other end. The inlet is preferably arranged atthe top of the casing and near one side therel located at the oppositeside of the ther end as indicated in the plan view of the device.Extending from end to end of the casing on the inlet side is a shield 71supported at the top of the casing a suitable shaft with cam fingers fwhich and extending diagonally toward th id in its rotatlon Wlll swingthe beams out and alinement with the dir crelease them simultaneously,when the and being out of tion of the inlet. This shield prevents anysharp particles which are carried into the casing from cutting thescreens. Such particles strike on this shield and slide down it droppingthrough the opening between the edge of the shield and the side ofthecasing to the bottom of the separator. The casing is divided into twochambers, the inlet chamber a and the outlet chamber a by suitablescreens through which air must pass in going from first to last, thesescreens being so fine that they will not permit the passage of the dust.The screens 0 which are of less width than the casing, are arrangedtransversely thereof as seen in Fig. 1, and extend substantially fromtop to bottom thereof as seen in Fig. 2. These screens are made upsprings f draw them back, causing them to strike the frame a sharp blowand shaking the dust to the floor of the casing, which is of funnelshape as indicated at g and equipped with a suitable slide door g forcleaning. A plurality of beams E and fingers f may be advantageouslyemployed as illustrated in the drawings.

- I claim as my invention:

1. In a dust separator, a casing divided into two chambers, by screensarranged in the form of compartments alternately opening in oppositedirections, one of said chambers provided with an. inlet orificeadjacent the top thereof, an obliquely arranged shield supported by thetop of the casing and out of alinement with the direction of the inlet,of the frame 0 on which there is tightly the said screens and rigidsupports therefor, stretched a fine gauze 0 through which the means forjarring said screens to remove the dust cannot pass. The frames aresecured dust therefrom and com arising a plurality at their rear edgesto the partitions a a of weights hung on swinging members from whichextend throughout the length of the said rigid supports, a shaft and aplurality casing to prevent the passage of the dust l of trippingfingers carried thereby and of, said casing and terminating adjacnt andjWitnesses:
